ELIATER PCIe Combo Serial Parallel Expansion Card PCI Express to Printer LPT Port RS232 Com Port Adapter IEEE 1284 Controller Card WCH382 Chip for Desktop PC with Low Bracket

A customer had his old computer died. It ran a laser engraver and a very old diamond engraver, both connected with a LPT Port only. I built him a new computer, but new motherboards don't have LPT ports, I I gave this a try. This was able to communicate with both using a splitter, customer is happy, so am I.

I was not sure if this adaptor would work before I order it. But the price is cheap, and I need to set up my backup PC for my business. Why not try? Both parallel and serial ports are working like charm. My business use a very old management software, 20 years old. And it checks a Marx security dongle through the parallel port. I only runs on Windows XP. Also it uses RS-232C serial port to connect the entire 15 pieces of equipment in my business. It all works nicely. Driver installation was just a couple minutes thanks to other customers tip, use CH38XDRV. Without their advice, I would've spent a lot more time. I only hope the board won't break at least for a couple years.

worked out of the box with windows 10.

Not a lot of documentation provided. Tried a couple of drivers on the CD and finally got it working with one of the WCH drivers. There’s two can’t remember which one I eventually used. Spent a morning trying all that out. It’s only a single serial and parallel board but two serial and two parallel have appeared on device manager. It works with my parallel port dongle which was my only requirement.

Installed into a Win 10 PC. It comes w. a CD filled w. drivers with no readme file to tell you which one to use.On Amazon's web site, where I bought it, included in the description of the card's virtues, it says to use the CH38XDRV. Once I did that, having wasted a good deal of time screwing around with other drivers on the CD, it worked fine. (This is a 1S, 1P card). If things don't work they say to contact the vendor/mfr. All I saw was a web site trying to sell me other stuff. with no contact info. Search CH38XDRV for newer driver from WCH = Nanjing Qinheng Microelectronics Co., Ltd.
